The TCK22923G is a device from the PMIC (Power Management Integrated Circuit) family, that allows for the power distribution, load switching and driving, as well as load monitoring. It allows for the automotive application field, for both 12 volt and 24 volt systems. The device works in the following way:

Load switching is performed by two (p or n channel) MOSFETs. This allows for a selectable on-off switching of the input and output pins, making it a useful way to switch multiple circuits from a single device. It also enables safe isolation of the input and the output, allowing for load separation when needed.

Load driving is done in two ways: low side and high side driving. The TCK22923G offers both low side and high side MOSFET driving. In both cases, the MOSFETs work as short circuits, and their voltage drop is very low (approximately 30 mV). This allows for efficient control of the power levels, as well as protection against short circuits.

Load monitoring is possible through a series of dedicated comparators. These comparators allow for accurate detection of the input voltage levels, either to detect over-voltage or under-voltage conditions. This provides reliable feedback to the system, and can be used for circuit protection.

The TCK22923G is ideal for automotive applications, where it can be used for controlling power distribution, load switching and driving, and load monitoring. The unique combination of the MOSFETs and the dedicated comparators make it a reliable and efficient solution for a variety of automotive applications.
